My daughter needs help with science can someone help her?

OpenStudy (anonymous):

sure ill try

OpenStudy (anonymous):

Its physical science

OpenStudy (anonymous):

ok

Which of the following is an example of a trend? the gradual warming of earths atmosphere over time the cyclic rising and falling of the tides. the phases of the moon the random assortment of coins in a jar.

OpenStudy (anonymous):

i think the answer will be the gradual warming of earths atmosphere over time

OpenStudy (anonymous):

That's the best answer, I think @warood is right on

OpenStudy (anonymous):

the 2nd and 3rd options are cyclical, so they reoccur (this is not a trend), random processes are also not trends

OpenStudy (anonymous):

the fact that the sun rises and sets at different times during the day depending on the time of year is an example of a data trend true **** false

OpenStudy (anonymous):

Its all yours @warood!

OpenStudy (anonymous):

the answer is true

OpenStudy (anonymous):

predictable amounts of rainfall in each of the 4 seasons is an example of a pttern true*** false

OpenStudy (anonymous):

thats also right

OpenStudy (anonymous):

a trend exists when data shows consistent reqular repetitive form true **** false

OpenStudy (anonymous):

im not sure wat do do u think neuro?

OpenStudy (anonymous):

i think its also true

OpenStudy (anonymous):

@Neuronerd what u think it is?

OpenStudy (anonymous):

I totally agree with @warood!

OpenStudy (anonymous):

patterns are recognizable and predictable events (not necessarily cyclical or gradual)

OpenStudy (anonymous):

is it direct?

OpenStudy (anonymous):

i think its indirect what do you think neuro?

OpenStudy (anonymous):

direct. First of all the logic is there (there is nitrogen in sewage) and the data confirms it by gradually declining the further away from the treatment plant

OpenStudy (anonymous):

It would be indirect if somehow the distance would cause something else to alter the nitrogen presence

OpenStudy (anonymous):

so its direct?

OpenStudy (anonymous):

But that's not the case here so its direct

OpenStudy (anonymous):

is this correct @warood?

OpenStudy (anonymous):

the amount of pollution in the nearby pond and the number of airplanes that fly over the pond have a non related relationship what will happen to the number of airplanes that fly over the pond as the amount of pollution increases?? increase decrease*** stay the same or responds randomly increase then decrease in a reqular pattern

OpenStudy (anonymous):

its kind of a misnomer to call it a 'non-related relationship' but this implies that one does not affect the other

OpenStudy (anonymous):

i think its stay the same or responds randomly

OpenStudy (anonymous):

I agree with @warood!

OpenStudy (anonymous):

okay so is it that than?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

Okay I have to leave, let us know if you need anything else or fan us to keep track!

OpenStudy (anonymous):

as the number of rabbits in a community goes up the number of foxes in the same community goes up this is an example of what type of realtionships? direct indirect cyclic non related***

OpenStudy (anonymous):

i think thats correct

OpenStudy (anonymous):

the leaves of a tree turn a deeper shade of red each fall depending on the amount of certain chemicals in that tree the greater the amount of there chemicals present in the tree the more red the leaves will turn what kind of realtionship do the shade of red and the chemicals in the tree have?? non related cyclic indirect*** direct

Hi Janice, to answer the first question about foxes and rabbits: this is an indirect relationship. Since there is no literal reaction that creates more foxes with the addition of rabbits, there is an indirect relationship as foxes prey on rabbits and are a staple in their diet. However, it is important to stress that this is indirect because one does not DIRECTLY cause the other. This is something along the lines of correlation DOES NOT equate to causation.

OpenStudy (anonymous):

To answer your last question: this is a direct relation since the red is directly related to the amount of a certain chemical (which I am assuming is a pigment like carotene, which causes the red appearance after the chlorophyll has run dry). Please let me know if that makes sense!
